Hi, First of all, NET-SNMP's "snmpwalk" and the SNMP GETBULK operation are two totally different things.
GETRBULK is similar to GETNEXT. Thus if you provide an instance OID (ends with .0) you will not get the instance but its successor (if available). snmpwalk works very differently and it is not worth the time trying to compare it with GETBULK.
